Unmapped Storage
Warehouses and cold rooms qualified by assumption — setpoint on the controller, no logger data. The hot spot near the dock door and the cold spot by the evaporator stay invisible until an auditor asks for the mapping study.

Service · GDP & Cold Chain Qualification
Validated at the plant. Unproven in transit.
Manufacturing gets the validation budget; distribution gets a thermometer and a prayer. We qualify the whole journey — thermal mapping of warehouses and reefers, summer and winter shipping lanes, packaging performance, and excursion investigations — across road, air, and water. So the product your customer receives is the product you made.
WHY NOW
The handoff is where evidence goes to die.
Regulators know it: FDA's sanitary transportation rule, 21 CFR 117.93 warehousing and distribution, and state cannabis distribution requirements all target the same weak point — what happens after the product leaves the dock.
Every handoffDock to truck, truck to warehouse, warehouse to last mile — each transfer is a point where temperature control can lapse and nobody owns the record.
Summer and winterA lane qualified in April fails in August. Shipping qualification needs both seasonal profiles, not one convenient test run.
One excursionA single undocumented temperature excursion can quarantine a shipment. Without an excursion procedure, every alarm becomes a crisis.
WHERE IT BREAKS
The four cold-chain failures we see most.
Distribution is audited against records. These are the records that don't exist.
Single-Season Lanes
A shipping lane 'validated' with one summer shipment. Winter profiles, heat-wave profiles, and the tarmac wait nobody modeled are where the qualification quietly stops being true.
Packaging by Hope
Insulated shippers picked from a catalog and never tested against the actual lane. ISTA 7D exists for a reason — packaging performance is a claim that needs data behind it.
Excursions Without a Procedure
The alarm goes off and the response is improvised: quarantine everything, argue about it, release on gut feel. No impact assessment, no documented rationale, no defense if the lot is ever questioned.
OUR METHOD
From dock to customer, qualified.
Four phases that turn distribution from an act of faith into an evidence package.
Thermal Mapping
Warehouses, cold rooms, and refrigerated transport mapped with calibrated temperature loggers. Hot spots, cold spots, and door-opening effects documented — the baseline every other claim rests on.
Lane Qualification
Your actual shipping lanes profiled in summer and winter conditions, across road, air, and water legs. Packaging performance verified against the lane data, not the catalog sheet.
GDP Procedures
Storage and distribution SOPs, carrier and 3PL qualification, monitoring and alarming routines, and change control — the system that keeps the qualification true after we leave.
Excursion Defense
When temperature leaves the labeled range: documented investigation, product impact assessment against stability data, and a defensible release-or-reject decision. Every alarm handled the same way, every time.
WHERE IT APPLIES
One method, five industries.
Cannabis is our home base — the method was built there first. The same evidence discipline serves each industry below, mapped to its own regulations.
Food & Beverage
Sanitary transportation practices and warehousing controls under the FSMA Sanitary Transportation rule and 21 CFR 117.93 — shippers, loaders, and carriers held to one standard.
Dietary Supplements
Warehousing and distribution controls under 21 CFR 111.470 — holding conditions that protect identity, purity, and strength through every transfer.
Cosmetics
Storage and distribution records that stand up under MoCRA — because a product that degrades in a hot warehouse fails the safety case it was sold on.
Pet Food
Warehousing and distribution of animal food under 21 CFR Part 507 — preventive controls that extend past the plant gate to the customer's shelf.
QUESTIONS
Cold chain, answered.
What is the difference between GMP and GDP?
GMP governs how a product is made; GDP — Good Distribution Practice — governs how it is stored and moved afterward. A perfectly manufactured product can be ruined by an unmapped warehouse or an unqualified shipping lane. Most distribution findings happen at the handoffs: dock to truck, truck to warehouse, warehouse to customer.
Do you perform the thermal mapping yourselves?
Yes. We map warehouses, cold rooms, and refrigerated transport with calibrated temperature loggers, identify hot and cold spots, and document the evidence — including seasonal profiles, because a space that holds temperature in April can fail in August.
We use 3PLs for warehousing and transport. Can you still help?
That is the most common model we see. We qualify your carriers and 3PL partners against your requirements, review their temperature records and procedures, and build the GDP procedures — excursion handling, monitoring, and change control — that make outsourced distribution auditable.
What about cannabis distribution specifically?
Cannabis distribution sits under state rules — licensed distributors, transport manifests, track-and-trace, and storage requirements that vary by state. We map your distribution operation to your state's actual requirements and qualify the storage and transport the way an auditor will check it.
Can cold chain qualification be combined with the GMP Readiness Assessment?
Yes. Distribution and storage are part of the assessment's evidence review, and a focused cold chain qualification bolts on cleanly — thermal mapping and lane qualification run in parallel with the four-week assessment cadence.
